Interesting thread.
I have considered ADHD as a diagnosis for myself over the years, along with other diagnoses - Asperger's, Dyspraxia' Bipolar! No, I promise I am not hypochondriac. But something has always been quite 'off' about me and I seem to have limitations which hold me back and cause underlying anxiety and depression...so I am always searching for answers that might fit.
I scored 40 on the test above, with inattention as the key feature.
Despite having held down some very responsible jobs over the years, buying a house and being married with two children, I have always been incredibly messy, unable to organise anything practical, somebody who loses and/or breaks things frequently and can procrastinate for England. I feel like an incapable child trapped in the body of a grown woman a lot of the time.
The post upthread about trying to get organised, having small success, then forgetting what you were doing/losing things/failing to be organised, then starting ALL over again and on and on...that really struck a chord with me.
I forget to pay bills and turn up for appointments, despite a diary with reminders. Its like my brain cant grasp certain information for more than a few minutes. I have never achieved a proper filing system for bills or important documents. My house is OK-ish, but our bedroom is a wreck because I just cant seem to be able to organise things like clothes and shoes properly. My desk at work was always a mess (not working currently), with papers stuffed in drawers. I have a never-ending to do list that I cannot seem to be able to prioritise and act on. Have also tried every self help guide, 'declutter your house/change your life' website etc. it helps for about a week max and then my brain sort of slides back into being scatterbrain.
I was like this as a child. I believe I am probably dyspraxic, too, as I am clumsy, drop/break/bump into things on a daily basis and always had very poor spatial awareness.
I have mentioned ADHD to a psychiatrist once, but was met with scepticism. I had a bipolar disorder diagnosis at one stage, but this is under review. I sometimes wonder if it IS ADHD and the depression I am prone to stems at least in part to having to work so hard to mask it and from beating myself up about how generally crap I am at life!
